[PATCH 3/3] powerpc/powernv: only call OPAL_RESEND_DUMP if firmware supports it

From: Stewart Smith
Date: Thu Feb 12 2015 - 00:25:58 EST


Not all OPAL platforms support resending system dumps, so check
that current firmware supports it first. Otherwise we get firmware
complaining:
"OPAL: Called with bad token 91 !"
